ABSTRACT
<p><b>OBJECTIVE</b>To detect the platelet glycoprotein-specific antibodies in serum of thrombocytopenia patients and evaluate its diagnostic value for immune thrombocytopenia.</p><p><b>METHOD</b>Anti-GPIIb/IIIa, GPIb/IX and GPIa/IIa antibodies were assayed by ELISA kit (PAKUTO) in patients with thrombocytopenia.</p><p><b>RESULTS</b>The sensitivity and specificity of PAKAUTO in immune thrombocytopenia were 44.0% and 95.7%, respectively. The values of positive and negative predictions were 98.0% and 26.2%, respectively. Among those PAKAUTO positive patients, positive rates of GPIIb/IIIa, GPIa/IIa and GPIb/IX were 87%, 35% and 10%, respectively. The positive rate of patients not received immune suppressive agents (58.5%) was significantly higher than those received immune suppressive agents (26.9%) (P < 0.01). The positive rate of patients with platelet count ≤ 20 × 10(9)/L (51.6%) was significantly higher than those with platelet count > 20 × 10(9)/L (27.8%) (P < 0.01). The positive rate of patients with secondary immune thrombocytopenia (66.7%) was significantly higher than those with primary immune thrombocytopenia (41.7%) (P < 0.05).</p><p><b>CONCLUSION</b>The highly specific method (PAKAUTO) could effectively differentiate immune or non-immune thrombocytopenia and be applied to diagnosis of immune thrombocytopenia.</p>
